Reactive Weather Example

Abstract

1. Introduction

A simple iOS weather app using the MVVM pattern and RxSwift framework.

#How it works There's a UITextField in the ViewController which sets a searchText property in the ViewModel once it's changed. The ViewModel then iniates a JSON request for weather data from openweathermap.org, and creates a new Weather object, which acts as the model.

Once the Weather object is set, properties in the ViewModel are set accordingly. Since outlets in the ViewController are bound to properties in the ViewModel, they get set automatically.

2. Objective

A simple iOS weather app using the MVVM pattern and RxSwift framework.

This project demonstrates how Swift can be applied to a real-world Mobile App Development problem.
